Oh thank God. You bought a new keyboard.
Anyhoo, the drums.
With only two mics you'd be better off maybe using one as an overhead and one as a kick mic. Yes; it's mono but, iirc, you're recording on a four track anyway and stereo drums would be a bit of an unnecessary luxury (imho).
As regards placement have the drummer play, walk around the kit and listen then stick the first mic where it sounds good (you're looking for a good balance between the various elements of the kit here). Then take the other SM57 and stick it in the Kick. Again moving it around while the drummer plays (just the kick in this case) until you get as close as possible to what you're looking for.
